Description:
------------
<?php
$xml = new XMLReader();
$xmldata = '<TestOne><tag>data</tag><tag>data</tag></TestOne>';
$xml->XML($xmldata);
?>

php 5.4.11 compiled with libxml2 2.9.0

/usr/bin/php: symbol lookup error: /usr/bin/php: undefined symbol: 
xmlTextReaderSetup

It works when php is compiled against libxml2 2.6.26 
XMLReader is not compatibile with new libxml2 version.

Cannot reproduce.

php 5.4.11 and 5.4.12 build against libxml2 and work as expected.

[2013-02-22 00:28 UTC] spamik at yum dot pl

I've tested with ONLY --with-libxml-dir=/usr/libxml2-2.9.0 and it does work. Some 
other extension (on my normal configure) must be interfering. I will try to 
determine which one with trial and error and soon let you know.

>>Problem appears when compiling with mcrypt and extension (and libxml2 2.9)<<

Package libmcrypt-devel-2.5.8-4.el5.centos.x86_64 already installed and latest 
version
./configure '--prefix' '/usr/share/php-5.3.21' --with-libxml-dir=/usr/libxml2-
2.9.0/ '--with-mcrypt
make install
<?php
$xml = new XMLReader();
$xmldata = '<TestOne><tag>data</tag><tag>data</tag></TestOne>';
$xml->XML($xmldata);
?>
/usr/bin/php: symbol lookup error: /usr/bin/php: undefined symbol: 
xmlTextReaderSetup

I've also tried compiling libmcrypt from source - no changes.

./configure --prefix=/usr/libmcrypt-2.5.8 --disable-posix-threads
make install
./configure '--prefix' '/usr/share/php-5.3.21' --with-libxml-dir=/usr/libxml2-
2.9.0/ '--with-mcrypt=/usr/libmcrypt-2.5.8'  

sill does not work (it works with libxml2 2.6.x for some reason)

[2013-02-22 01:38 UTC] spamik at yum dot pl

also during make install (php) i see

./configure '--prefix' '/usr/share/php-5.3.21' --with-libxml-dir=/usr/libxml2-

I did not linked to usr/lib64/libxml2.so.2 !! Some error in linking (but only 
when mcrypt is present)

[2013-02-22 01:56 UTC] spamik at yum dot pl

I would guess that mere presence of --with-mcrypt on configure breaks linking to 
custom libxml2 directory (--with-libxml-dir=/usr/libxml2-2.9.0/) and it defaults 
to system /usr/lib64 (and there is distro standard old libxml2 there which break 
things).

[2013-02-27 03:15 UTC] veillard at redhat dot com

just to point out that xmlTextReaderSetup is not part of libxml2
ABI, nor on current version nor on 2.6.26.

thinkpad:~/XML -> grep xmlTextReaderSetup doc/libxml2-api.xml 
thinkpad:~/XML -> 


[root@test-rhel55 ~]# gunzip -c /usr/share/doc/libxml2-devel-2.6.26/libxml2-api.xml.gz | grep xmlTextReaderSetup
[root@test-rhel55 ~]# 

it would be good if PHP didn't use name which looks like that they are coming
from libxml2 even if they are possibly wrappers around libxml2 functions.

problem seems to be caused by flag -lltdl. When removed manualy, libxml2 is liked ok. What is this flag?

[2013-06-13 08:55 UTC] derick@php.net

It's a linker helper library as used by gnu libtool. I have no idea why it messes the libxml include though, and as far as I know, that library is no longer needed since libmcrypt 2.5.4. So unless your version is that old, -lltdl should not be part of your Makefile. If I manually remove -lltdl from the Makefile, PHP still compiles and links, so I would recommend you try the following:

cat /usr/include/mutils/mcrypt.h | grep VER

And let me know what it says. Secondly, apply the attached patch to ext/mcrypt/config.m4 and then run:

make clean
./buildconf --force
./config.nice
make

and see which libxml it now links too.
